Roulette is a casino game that involves betting on different groups of numbers. The payouts for winning bets vary. There are several types of bets, including announced bets.

Players place chips on a betting mat to indicate their bet. They can continue to make bets until the croupier announces no more bets.

Origin

The origin of roulette is a mystery. There are many fanciful stories about its invention, including that it was invented by 17th-century French mathematician Blaise Pascal, or that it is based on an ancient Chinese game brought to Europe by Dominican monks. In fact, the modern version of the game probably derived from older games such as hoca and portique, and it achieved its current layout and wheel structure after several modifications. The game is now a staple in casinos and gambling houses around the world.
